On 20 July 1969 NASA's Apollo 11 mission landed the first humans on the Moon, with Neil Armstrong and Buzz Aldrin walking on the surface while Michael Collins orbited above in the command module. The landing was the climax of the Cold War space race between the United States and the Soviet Union, fulfilling President Kennedy's 1961 goal of reaching the Moon within the decade. It depended on the giant Saturn V rocket and an immense programme of systems engineering, with hundreds of thousands of workers and contractors. An estimated several hundred million people watched the event on television worldwide.
It stood as a defining demonstration of technological capability and a decisive moment in Cold War geopolitics. Beyond its scientific yield, it reshaped popular imagination and entrenched the large-scale, systems-engineering and project-management ethos that also influenced ambitious planning of the era.
